The purpose of this prospective study was to describe cementless humeral surface replacement arthroplasty (CHSRA) as a bone preserving treatment option for patients with fixed anterior glenohumeral dislocation. Ten patients with post-traumatic fixed anterior glenohumeral dislocation underwent CHSRA with a mean follow-up of 24 months. All patients were evaluated clinically using the Constant score and with radiographs in two planes. There were two reoperations: one patient developed glenoid erosion and was revised and in another case redislocation occurred. Clinical or radiographical signs of implant loosening were not found. The humeral head centred in the glenoid in nine out of ten cases radiographically. The Constant score increased from 20 points preoperatively to 61 points postoperatively (p < 0.007). CHSRA is a viable treatment option for elderly patients with fixed anterior glenohumeral dislocation and bone defects of the humeral head. Good clinical results and a moderate complication rate were found in the short term.
本前瞻性研究的目的是描述非骨水泥型肱骨头表面置换术（CHSRA）作为一种针对固定性前盂肱关节脱位患者的保骨治疗选择。10例创伤后固定性前盂肱关节脱位患者接受了CHSRA，平均随访24个月。所有患者均使用Constant评分进行临床评估，并拍摄两个平面的X线片。有2例再次手术：1例患者出现肩胛盂侵蚀并进行了翻修，另1例发生再脱位。未发现植入物松动的临床或影像学征象。10例中有9例在X线片上肱骨头位于肩胛盂中心。Constant评分从术前的20分提高到术后的61分（p < 0.007）。CHSRA是老年固定性前盂肱关节脱位且肱骨头有骨缺损患者的一种可行治疗选择。短期内获得了良好的临床效果和中等的并发症发生率。
